A) Zero
B) \[\frac{3GM}{{{L}^{2}}}\]
C) \[\frac{9GM}{{{L}^{2}}}\]
D) \[\frac{12}{\sqrt{3}}\,\frac{GM}{{{L}^{2}}}\]
Correct Answer: A
Solution :
Due to three particles net intensity at the centre \[I={{\vec{I}}_{A}}+{{\vec{I}}_{B}}+{{\vec{I}}_{C}}=0\] Because out of these three intensities one equal in magnitude and the angle between each other is\[120{}^\circ \].You need to login to perform this action.
